Geology is thrilling. It's the Earth in all its splendor. Unfortunately, geology texts rarely communicate that sense of excitement. Enter Michael Collier, geologist, writer and one of America's premier aerial photographers. For over 20 years, he has piloted his Cessna 180 to inaccessible locations and returned with stunning photographs that lay bare the Earth's workings. Over the Mountains, the first book in Michael Collier's new series, focuses on geology's most spectacular subject in a most spectacular way. It includes: Detailed and breathtaking large-format color photographs covering the geology of every major mountain range in the United States Clear, easy-to-understand text, diagrams and captions that explain and illuminate the geologic processes shown in the photographs. After exploring the pages of Over the Mountains, readers will never think of mountains -- or geology -- in the same way again.
